In Chrome it looks good but it don't works in IE. In IE i get these errors:

Code:

[E] You have set frame: true explicity on this component (window) and it does not have any framing defined in the CSS template. In this case IE cannot figure out what sizes to use and thus framing on this component will be disabled.
[E] You have set frame: true explicity on this component (header) and it does not have any framing defined in the CSS template. In this case IE cannot figure out what sizes to use and thus framing on this component will be disabled.
[E] You have set frame: true explicity on this component (button) and it does not have any framing defined in the CSS template. In this case IE cannot figure out what sizes to use and thus framing on this component will be disabled.

So there is something wrong with the CSS and IE9? Help needed, thanks.

yes you are right. If i move the whole block just behind the Ext.onReady call it works. There are a few functions and defines just before the login form. Strange behavior! So the order is important in IE.
